To all whom it may concern: j v

Be it known that I, ANDREW P. TUCKER, a citizen of the United States,residing at the city of Cincinnati, inthe county of Hamilton and Stateof 'Ohio, haveinvented cer-' tain new and useful Improvements inMachines for Making Paper Forms, of which the followingis aspecification; j

The object of my invention is to produce a simple and highly "efiicient,rapidlyoperating machine-for making paper forms, in the present instancemore particularly applicable to the manufacture of trays for eggcarriers; I also having invented a machine for making egg carrier"bodies into which {such eggtrays fit and with which I they combinetomake the finished'egg carrier and for which machine I have applied forLetters Patent Serial N 0. 39,250. i Q

In my present invention I arrange and combined sets ofrolls, scoringknives, paste appliers, folding devices, cutting knives andforming-rolls, in'a unique, novel and efficiently operating combinationin erder to produce satisfactory results in the marine 'facture of paperforms, the "machine 'operating automatically. Its variousfeatures andadvantages will readlly become apparent from the followingspecificati0n.-

l I form the'frame-of the machine of two Sl'ClBfPzUIltB pieces 1-1,pinned and connected together in any suitable manner. In these frames-1,-1, and extending entirely across the machine, I place the drivingshaft 2, carrying pulley 3, and a small drivegear 4; I similarly supportthe eccentric shaft 5, ."carrying" the eccentrics 6-6, and gears'l, 8and 9,the gear 7 beinga large gear, gear 8 being somewhat'smaller andgear 9 being a bevel gear; and I further provide shaft 10, which'carriestwo gears 12 and 13, gear 12*bein'g on inside of frame 1 andgear 13 on the outside thereof. The above shafts are properly journaledin the sides of the machine in suitable bearings.

On the outside of the frame ofthemachine I journal on studs, see Fig. 1,a num- 'ber of gears or idlers, as follows; on the stud 1 1 Icarry theidler gears 15 and 16, Qnstudl'? I carry idlergear 18, on stud 19I'carry idler gear 20, on stud 21- I carry idler which I will nowdescribe. I provide brackets or housings 25, which support the shaftswhen the hand wheel 32 is turned, said hand wheel being on shaft 27ofthe lower roll;

by this'aneans the paper 33 is started into' theinachine, Inshortbrackets or housings 34", I support the shaft' 35 on which is a roll 36whichfoperates to pass thepaper'under these knives are each gear 22 andon stud 23I carry idler gear 241. On thetop of the machinev or frames-l1, I placebracketsor housingsfor supporting the shafts and rolls andtheir bearings,

supported on apin 38, which pin, in eachin stance, is carried by ajaw'39, which jawat 'its'upper extremity passes through, a sleeve -l0,on top of which is a "finger sil through which an adjusting screw 42passes thus Y permittingvertical adJustment of thescoring knives orwheels. Through an arm 43 on'the sleeve 10. passes arecessfthrough theagency of which the scoring knives 37 are slipped onto or over thesupportingbar 1 1 which is supported in brackets 45 which are onthebrackets 34 above referred to; and on the shaft 35, I place a gear 46which operates "the'lower roller 36, to feed and support-the ice ' shaft49, thisshaftcarrying the paste roll lower roll 63 which issomewhat'short'er 54, the said roll acting as an intermediate feed rollas the paper 33 is passing over the paste roll 54, the paste roll 54also acts as a feeding roll but for convenience it is called a pasteroll. The paste roll 54-.at

, eachend iscut away and here I place a series of rods or fingers 55. IOn the inside of frames 1 1-,I connect, at each side, a paste trough orreservoir 56-;into which the fingers pass to receive the paste at eachrevolution, and as the paper 33 is passing through the rolls50 and 54andover the fingers 55, a series .ofpaste dots or spots are received bythe paper at eachedge thereof; on the said upper shaft 48, I carry agear 57 which'meshes with gear '53 which meshes with idler gear22 andthuslthelrolls 51 and 54v are revolved. Inanother setof bracketsorhousings 58; I journal shafts T59 and, 60, 'theshaft 59 carryingtheupper roll Gl which at each end is formed with a flange 62, and theshaftGO carries the than roll 61, so that it will just'come withinthefianges .62. to allow for thethicknessof V :the paper 33 betweeniitsend and the inner faceof the flange 62, so that when the rolls 61 and 63revolve, the paper 33 is folded or bent over at practically a rightangle, which isgthe first fold for the paperon: its passage through themachine, (see particularly Fig. 8). On the shaft 59 I carry gear'64 andon shaft .60 I carry a gear 65, the gear 65 meshing with the idlergear'20 and thus the ;rolls* are revolved. These rollers may be calledithefolding rolls. The turn.. dow n edge made-by these rolls ismarkedtti,(see particular Fig. a

' Inbrackets 67,.1 carry and support a folding device 68, which foldsthepaper edge y6 61into its final form or fold as shown by dotted linesingFig.;9. This folding device 158, at each side of the machine has aninclined slot 69 into which the paper' enters fthe slot gradually:diminishes in depth; 65 untilthe final fold; of the paper isreached asseen v in dotted lines in Figs. land 9.. The

paper when lthus folded has a double edge ateach "side thereof? Ifurtherj-provide brackets or housings 70, in which I ournal 6' andsu'pport two shafts- 71 and 72,.the shaft 71 carryingfa sector roll 73and theshaft 7 2carryingthelower roll 74, the sector roll 73 having thecut away face or section 7 4; at its outer end the shaft 71 carries the;gear 75 andthe shaft 72 carries the. gear 76, said gears, meshing; andthe gear 7 6. meshing with the idler gear '16, thus these rolls'arerevolved. These. rolls are used as feed rolls and also as-pressure rollsfor pressing the edge 66, which has. been pasted and further folded downonto, the paper 33 and now the The doubleedge is shown in Figs. 10 and1.1.

In the brackets or housings 77, I support a carriage 78 which carriesthemale perforating die 79 which operates-to punch or paper hasa doubleedge on "each side, so I that the ends of the egg tray form when formedwill be strong and firm.

perforate the paper 33 in connection with' female dieSO, into a contourand configura- .tion as shown in Fig. 11. The carriage Y8 ,carrying themale die 79 moves downand "up' to formthe female die 80,:through theagencyof eccentrics 6 and'eccentric arms 81, which attheir lowerextremity are pinned at the point 82 to the eccentrics 6, and at theirupper extremity are pinned to the car- 'iage 78 .atthe point 83, theeccentric arms being provided with locknut adjustment 84.1 ,On the diecarriage 78 I suitably support and connect a-severing knife 85 whichcuts astrip off of the main sheet 33, outof which the egg tray forn isPTQSSdv Wh le this oerforatin and-cuttin is aro ressin the .t'fl 2') :5.tDJ

cut away faces 74 and 51 orrthe sector rolls 73 and 50 resepctively, arenot in contact with their co-acting rolls, and so the feeding 10f thepaper is momentarily stopped, so that the dies and cutting knife can do.the1r workpthen as soon as the sector rolls again contact with theircoacting'flor operating rolls, thepaper 33 again begins to feed forwardandjthisaction-isrepeated again and again; r

Theicarriage 7 8 and the knife 85"'recei ve their motion by reason ofeccentric shaft 5,

revolving on; account of the gear 7 on said shaft meshing with gear 4 onshaft 2, which inturn receives its motion from the driving pu lle'y 3.lVhen thestrip is cut it lies .01 rests in 5a guide tabled- 86 which hasan" elongated slot 87,- the strip lying in the guide table in;Fig s. 3andf12 is marln'edv88.

The-guide table 86 rests on a supporting b-racket89, onthe bottom'ofwhich I place a bearing 90, throughwhich passes a short 'shaftz9l',carrying at each end a sprocket wheel as .92 and 93. ()n the supportingbracket 89, I also place a hearing94, carrying "asprocket 95,;(seeparticularlylfigs. 2

' and 3) on a shaft :96. 1 .Onajshortshaft97, I .place another sprocketWheel 98, which short-shaft is revolved by reason of bevel gearlOlmeshing with'bevel gear 9 on shaft 5. A sprocket chain 99passesgover'"sprockets 98 and 93 and turn'sshort shaft 91, and

a sprocket'chain' 1 00 passes over .sprockets 92 and 95 and--thuswthejshafts 96 and 91 a reflrevolved. On the sprocket chainlOO, Iplaceia push. finger 102 which pushes the strip 88 to theforming rollsto be hereinaflee ter described. The finger 102 operates through theslot103 along with-the said sprocket chain 100. I further provide largebrackets 01' housings 104c in which I journal two forming rolls 105and106, the roll 105 being the male and the roll 106 being the female roll.The male forming 'roll 105 has a series of formers 107 on its face andthe female, roll 106 has a series of depres sions' 108 on its face, theformers 107=fitting into the depressions1'08 to press the paper betweenthem into final form; Onone end of the roll 105, I place the gear 109and at one end of the roll 106 I placethegear 110 which mesh with: eachother, the gear 110 meshing with gear 112, on stud shaft 11st which iscarried in the bracket 115, which meshes with a gear 113. on shaft 97this shaft 97 is turnedby .bevel gear 101 meshing with bevel gear 9--'onshaft '5, which shaft is turned by gear 7mesl1ing with gear lon shaft 2,which is operated by and carrice the driving pulley 3. a

It will not be necessary to give a 'full -detailed account of theJoperation of the machine here, as the operationof :various. parts hasbeen pointed out as they have been described andthe operation ofthemachine will be readily understood. i

The lines scored by the scoring, knives are marked 120 as will beplainly seen in Fig. 11, the scoring however being donexon the fullsheet before it is cut into strips. The end or sides of the sheet whichis folded as it passes through the"machine is plainly shown in Figeillwhere the sheet before beingfolded is marked-122 at its edge and afteritis"foldeditapp'ears as'seen in Fig. 10 marked 123,115 will beunderstood of course that. this folding is done before the sheet is cutinto strips.

The paper form or egg tray, after it has passed through the formingrolls last de scribed is finished andeither falls ofli the former rollsor is reniovec'l bystrippermechanism (not shown), of any. convenientform. From the rolls it passes off by endless belt or otherwise out ofthe way of the machine. It will be noted that 1 operatedon a full sheetthrough the machine and when the strip is cut off of this full sheet, itis moved laterally or at right angles from the other part of the machineand passes to the rolls to be formed. I may heat the forming rolls 7 andmoisten the paper, if I so. desire, as

tion, enables me to produce the articles quickly and uniformly. Theserolls, the dies -theicutting knife, the pasting device,

the pressure rolls, the folding devices and the'final forming rolls, areall "timed to operate at the proper time to carry their motions-andoperations into effect, and this enables meflto operate the machine veryproduce the paper forms in and it will also be obvious. from the abovedescription that theinachine is capable of considerable modificationWithout material departure-from the principle and spirit of theinvention, and for this reason I do not wishlto be understood aslimiting myself tothe precise form and arrangement of the several; partsofithe' machine'as herein set forth in carrying out my invention in'prac-' 1. i /hat I claim as new and my invention and desire to secureby Letters Patent is-- i 1-.
